Left Hand Dyad Casement Window Operator for Wood Windows, Offset Down Link

Left Hand Dyad Casement Window Operator with Offset Down Link for Wood Windows

This is a split arm dyad operator designed for wood casement windows, manufactured by Amesbury Truth Hardware. The operator features a 3-61/64" (100.8 mm) long link, which is offset down, with the clip positioned on top for secure attachment. It is intended for left-handed operation, making it important to match to your existing window setup. Frequently used in Truth® and Entrygard® branded systems, this operator is commonly found in residential and light commercial wood window frames.

The housing and link arms often display specific numbers, such as housing #30471, first arm #30636, and link #20544, although these may vary depending on model year or factory production run. The offset and clip location can differ, so close comparison to your existing hardware is important for proper fit and function. This product is specifically the left-hand version (part code 55063), with an opposite-handed variant available for right-hand applications.
